I was experiencing sluggish performance on my s6, it was taking ages for my contacts to appear when trying to dial them, I fixed this by going on to apps>contacts>clear data and cached data. However it came at a price. many of my contacts have now disappeared. is there anyway i can restore them?

I have a samsung galaxy s6(sm-G920F) on 5.1.1 non rooted, the problem i am facing is that the lte stopped working without any reason, I didn't drop it neither i updated anything it just stopped working now i only see the E sign on the network bar.

So basically i woke up one morning with no contacts in my phonebook when i had about 50 the day before. So i now have no numbers and also it won't let me save contacts either :| i re-add a contact, it says saved, but then returns to the 'add a contact' page.

My samsung galaxy SII had been playing up, crashing etc for a couple of weeks, then for some unknown reason, it froze and died on me, never to be switched back on again. It has been well looked after so it hasn't been water damaged or dropped or anything of the sort. The battery was about 50% charged, I've also tried using somebody else's battery, tried connecting it to a PC, tried to start it whilst its connected to the charger and everything else I could think of but nothing. My main problem, is that I've been in touch with samsung and they asked to send the phone to them for repair, but told me that everything will be erased.

Now I know I am totally stupid for not backing up all of my media etc, but the information stored on the phone is worth more to me than what the phone is itself. Although the phone is totally dead and will not switch on, so how I can access my pictures/videos etc because surely it must be still stored on the phone somewhere. The phone itself is not as important to me as much as the media stored on it and I am willing to try anything to access my media files even if it means my phone isn't able to go for repair, I know I am going to receive comments for not backing up my media.

I have the EE variant of the G920F galaxy s6 in the UK. At least once a day the phone will reboot for no apparent reason what so ever. This has been since the 5.1.1 update, I have factory reset and cleared cache and it still happens. Thinking of flashing the international software to see if it happens with that.

My Samsung S6 is only a month old. Hasn't had a problem with it once an all of a sudden went to pick it up an i couldn't turn it on, Plugged it into the charger an still not able to turn it on. The charging signal doesn't even turn on. What can i do?

All contacts on C7 just disappeared, i tried syncing with my OVI store it didnt solve the problem. i then opened my OVI account on my system i noticed that i couldnt get any contacts there again,my fear is that i might have synced my OVI account with zero contacts.

I got an HTC One two days ago and transferred my contacts, music and photos from my old phone (a Samsung Galaxy S) using the HTC Transfer tool. It worked like a charm - or so I thought. After trying to send a text today, my entire contact list was completely gone, and the phone is telling me it has zero contacts stored in either phone storage or on the SIM card.

The contacts were there four hours ago. My call history is also deleted, but my texts messages are still saved. Even stranger is that the photos and music that were transferred are still there. Luckily I still have my old phone and can transfer the contacts over again, but it's odd this would happen at all. I'm wondering if it may have to do with google+, as I switched over sms to google+ hangouts this morning on the phone (but I can't see how this would make a difference).

I changed my primary email for my apple id and installed find my friends. I configured iCloud and mid text, all my contact names disappeared. In iCloud.com I have no contacts, on my phone I have no contacts, and I did not back up anywhere.

My wife's icon for her Contacts is not on her home screen. She didn't make any folders, so it's not there. When she "Search iPhone" and type "Contacts", the app appears and she can add/edit contacts that way. Where did it go?

I've lost all my contacts for the last 2 years. Any way to get them back? I saw several questions saying this was caused by iCloud but i had no chance to register if it is not created automatically. I used the one (just forgot how it was called - the one that syncs all apple products and which was inactivated in a few days) - maybe it is because of this? But i dont think - it should not be this.

i keep not being able to find my contacts when i scroll through the list but they would come up when i search. to try and fix this i went into the menu and changed the sort order to first name first as it was surname first. it has now deleted most of my contacts, leaving mostly only the ones that do not contain phone numbers (i think my gmail ones) and i cant find a way of getting them back. Strangely, at first some still came up when i searched but now (i'm not sure what i did in the process of trying to fix it) now there is definitely nothing there. I had not yet set up icloud so they are not stored there but may be in an old google account from my old phone which isnt showing up even though gmail is set to sync.

I do not know what I did, but I suddenly have no contacts in my phonebook. However, I still have the original list on my simcard. If I try to copy them to my phonebook, nothing happens and the contacts doesn't appear on my contactlist. It also seem as if it is all the most used contacts that are missing.

When setting ring tone adjustments through the ring icon or when editing the contacts folder too quickly, the folder disappears from the main screen and is always replaced by the yellow pages app. I have searched all folders and it cannot be located. However, the info can be accessed by telephone or e-mail settings. If I pull the battery and reboot it is restored. Bell told me that it was a hardware issue, but replacing the phone still has the same issue. I have finger mobility issues, so I tried assorted battery pull and restart apps, but either they just don't work on the 9550 or they only work once. Hopefully when OS6 is released this will be remedies, unless any one can suggest one.

So I woke up this morning and suddenly ALL my contacts were gone. My phone log was wiped as well. I did not install any apps or alter any settings last night. ¬†I've checked the filters, that's not the problem (and it shouldn't affect the phone log either, right?)¬†I've tried closing the "contacts" app and clearing the data, that didn't do it either.¬†How to restore my contacts and/or prevent it from happening again?¬†Xperia Z3

I was just going to call my wife, but realised that she was gone from my contacts and not just her but all my contacts, yikes! So I checked the adressbook on my iMac and on iCloud and there are no contacts there either.

I have an iPhone 4S. It is on the current IOS 5.1 (9B179). Everything has been working fine, but earlier this week, I lost all of the contacts associated with my Yahoo account. I have tried the following:

- recycled the iPhone (full power down)

- turned off/on the contracts for the Yahoo account

- dropped the Yahoo account completely and readded

- confirmed that the contacts are still on the Yahoo account (via browser)

- confirmed that the contacts are visible on another device (iPad 1 with latest IOS version)

- waiting >24 hours with the Yahoo account re-added to determine if it would resolve itself

In all cases, the net result is the same. The iPhone can connect to the Yahoo account fine (email and calendar are no issues), but when selecting all contacts or even the Yahoo specific contacts, the iPhone is blank, but the account has >100 contacts.

My wife told me that I should load a lot of Apps. When she gave the phone back, there were no phone contacts. She told me she could sort it, but all I have is the SIM contacts which are a long time out of date. I have at least 50 missing numbers. They do not seem to be available through iTunes. Can I retrieve them from somewhere on the phone?

My contacts app disappeared, but the contact info is obviously still in phone bc you can see it in the phone, email, msgs etc.. I tried going under settings.general.reset.reset home screen. It pulled everything in the world back except the contacts app!
